From one of the documents, to quote: "Similarly targeted document subpoenas or deposition notices to any other third party who SCEA learns may be involved in the distribution or sale of the PS Jailbreak software, known as, for example, PSGroove, OpenPSJailbreak, and PSFreedom, or who may have knowledge of the distribution or sale of this illicit software."

PS3 hacker Mathieulh is also mentioned in one of the documents as recently proclaiming to be one of 20 individuals behind PSGroove, to quote: "Mathieu Hervais told BBC News he was one of about 20 hackers involved in PSGroove's development."

Just under a month ago Sony was granted an injunction by Australian Courts on the sale of PSJailBreak PS3 modchips, followed by blocking PS JailBreak and PS3 proxy methods with the release of the PS3 Firmware 3.42 update, so only time will tell what their next move is.
